As of May 27, eight state Senators had announced their retirement or candidacy for another office. That means at least one-third of next year's Senators will be new to the office.
The Senators not seeking re-election include Republicans Jeannie Forrester (District 2), Sam Cataldo (District 6), Jerry Little (District 8), David Boutin (District 16), Russell Prescott (District 23), and Nancy Stiles (District 24). Democrats David Pierce (District 5) and Molly Kelly (District 10) are also leaving the Senate.
Without those incumbents, Senate District 2 and District 24 both have a good chance of switching from Republican to Democratic control. District 2 is considered a swing district, while District 24 has leaned Democratic in other elections.
Other Senate incumbents will have to battle to keep their seats. Democratic Sen. Andrew Hosmer won District 7 by just 155 votes in 2014. Rep. Harold French has already decided to challenge Hosmer in November.
The result of these close races may ultimately be decided by which presidential candidate best mobilizes voters. In the 2012 election, voter turnout for President Obama helped Democrats pick up seats in the state House of Representatives, Senate, and Executive Council.
